Amyotrophic Lateral Sclerosis (ALS) (also known as Lou Gehrig's disease) is the most severe disease out of a group of degenerative diseases that affect the nervous system.
ALS destroys motor nerve cells in the brain and spinal cord and as a result, within a period of three to five years, the muscles in the limbs and those responsible for speaking, swallowing and breathing are severely weakened, eventually resulting in total paralysis.
Treatment is primarily focused on quality of life and generally includes physical therapy, as well as therapies for swallowing, speech, and breathing, in addition to emotional support. Many different forms of treatment help alleviate the symptoms associated with ALS, which include tightening of the muscles, shortness of breath, saliva build-up, pains, lack of sleep, and emotional distress. There are also many devices and accessories which help improve the quality of life for those with ALS and enable them to move and communicate.
